Nothing is coming from fluid inflow in Blender 2.8
It looks like the problem is that the inflow object is a circle curve with no face geometry. The fluid simulator will need some face geometry in order to generate fluid. The circle can be filled in Edit Mode by selecting the entire object and using the 'F' hotkey to fill in the circle with a face.

Note: your Domain Viewport setting is set to display Geometry. This mode will not display the fluid in the viewport and will just show the domain box geometry. Setting this mode to Final will show the final quality fluid result in the viewport.
